Is it ok to mix foliar treatment solutions?
I have a few different products that I use to keep my plants free from disease and pests, which I apply as foliar sprays. I also do foliar feedings as the season progresses. I keep them on a rotation so as to increase effectiveness, but it's a bit of a pain to keep track of when I've done each and to transfer the solutions from their storage containers to the one sprayer that I use. I'm wondering if it's ever ok to mix these products just for convenience sake. Currently, here's what I am using:
A mix of Actinovate and Excel LG (fungicide)
Bonide Copper Fungicide
Safer Caterpillar Killer (BT)
Neptune's Harvest (kelp/fish emulsion food)
Can any of you more experienced gardeners give me some feedback on this?
